Lattice width directions and Minkowski's 3^d-theorem

Research output: Book/ReportReportAcademic

Abstract

We show that the number of lattice directions in which a d- dimensional convex body in Rd has minimum width is at most 3d -1, with equality only for the regular cross-polytope. This is deduced from a sharpened version of the 3d-theorem due to Hermann Minkowski (22 June 1864-12 January 1909), for which we provide two independent proofs.
